Artificial lighting is considered one of the most important elements contributing to the waste of electrical energy، which has become a problem of the times، especially with the acceleration of demand for it and high consumption rates. In contrast، natural lighting has become the focus of those interested in saving energy، with the weakness of sufficient efforts to raise the value of using natural light optimally، whether in the design of buildings or legal legislation، which creates the problem of relying on artificial lighting and wasting energy، especially in educational buildings. Reasonable solutions for natural lighting during the day require an integrated and thoughtful design approach that achieves sufficient proportions and standards required for each space according to its function. We must also be aware of how the sun affects us and our lifestyles and realize this in the design of buildings by entirely dispensing with artificial lighting. Therefore، this paper aims to raise awareness of the importance of natural lighting in the initial stages of architectural design and its impact on the quality and efficiency of lighting design to solve the problem of energy dependence by introducing computer applications specialized in lighting design and renewable energy. The study will focus on solving the problem of insufficient natural lighting in drawing studios as a case study to reduce the use of artificial lighting through a practical study (using the professional DIALux evo program in lighting and energy design) to calculate the amount of natural lighting، evaluate it، and prepare a design proposal within one of the drawing studios in the Department of Architecture and Urban Planning، Faculty of Engineering، University of Tripoli. Based on the results of quantitative and qualitative analysis، the study concluded a set of results، including a deficiency in the amount of natural lighting by 136 lux and the necessity of increasing the amount of natural lighting by 614 lux to reach the equivalent of 750 lux، which is the required lighting standard.
